What type of products typically utilize pheomelanin?

Pheomelanin is a type of melanin responsible for the lighter pigmentation found in some hair colors, particularly red and blonde hues. This pigment is essential in hair dyes as it can create and enhance these specific hair colors. Hair dyes are formulated to work with the natural pigments in hair, and pheomelanin plays a crucial role in achieving shades that are typically associated with lighter hair. In contrast, skin moisturizers, sunscreens, and nail polishes do not specifically incorporate pheomelanin, as their primary functions and formulations do not involve hair color or pigmentation in the same way that hair dyes do. Thus, the connection between pheomelanin and hair dyes distinctly supports the selection of this option.
